1) Connect the Combi to COLD WATER
2) Never connect the Combi to HOT WATER! The Condenser system and the steam generator will not work properly if connected to HOT or WARM water.
3) The water supply must have a minimum dynamic (flow) pressure of 35 psi (2.4 kg/cm²) and a maximum static pressure of 60-psi (4.1 kg/cm²).
4) If the static pressure is above 60 psi, a pressure regulator must be used and set at approximately 50 psi. Pressure above 60 psi can damage solenoid valves.
5) Combis are supplied with two connection points for incoming water: condenser, and generator or spritzer.
6) If water supply meets requirements shown in Table 2-3 then the Single Water Supply Arrangement shown in Figure 2-10 may be used.
a) If the Single Water Supply arrangement is used: Supply piping to the Water Distributor (cold water supply splitter) (Order Number SPN), or similar tee fitting must be at least next largest size of pipe than the connection provided at the Combi.
7) If water supply fails to meet requirements shown in table 2-3 then use Separate Feed Water Supply Arrangement shown in figure 2-11.
8) Installation Requirements:
a) Apply non-hardening pipe sealant to all the threaded connections except the ¾” GHT Female (Garden Hose Thread or National Hose Thread) connections at the Water Connection. GHT or NHT connections do not require pipe sealant.
b) Install a manual water shut-off valve (not provided) between main cold water supply line(s) and Combi supply lines.
c) The National Sanitation Foundation (NSF) requires installation of a check-valve (or other approved anti-backflow / anti-siphon device) (not provided) in all supply lines in accordance with and as required by local, state, and national health, sanitation and plumbing codes.
d) Consult local codes to determine exactly what type of anti-backflow / anti-siphon device is necessary to meet local requirements.
b. Testing Water Supply Lines 1) Check all connections for proper tightness. 2) Remove side panels to inspect water connections inside the Combi. 3) Open the water supply valves. 4) Check all lines and connections for leaks, both inside and outside the Combi. 5) If Startup and Checkout will be performed next, leave side panel off; otherwise,
replace the side panel and secure it to the Combi.
